I’m in Denver and it has dropped to -10 degrees here the last few says. There are Teslas everywhere here and I haven’t seen or heard of this happening here. Also my nephew drove his EV Polestar from Denver to SLC on Saturday and had no problem with range or charging.
Here it’s Teslas, Rivians, BMWs, Bolts, et. al. but not a single one in that lot I was talking about the past few days (and I looked!).
